Answer:
The probability is 3/95
Step-by-step explanation:
Okay this is a probability without replacement question.
Firstly we calculate the total number of coins = 7 + 9 + 4 = 20 coins
The probability that the first coin will be a dimes = number of dimes/total number of coins = 4/20 = 1/5
Now she removes a coin without replacement, if it was a dime, total number of coins becomes 19 and the total number of dimes becomes 3; Thus the probability of the second coins being a dimes = 3/19
Thus, the probability of both coins being dimes = probability of first coin being dimes * probability of second coins being dimes
= 1/5 * 3/19 = 3/95
Cut each sandwich into pieces of thirds
4 sandwiches x 3 pieces = 12 total pieces
--------------------
12 / 6 = 2
Everybody would get 2 pieces
Answer: b. 8.56 to 21.44
Step-by-step explanation:
Let 
be the mean number of pushups that can be done.
As per given , we have
Sample size : n= 10
Degree of freedom = n-1=9
Sample mean : 
Sample standard deviation : 
Significance level : α=1-0.95=0.05
From t- distribution table ,
Critical two -tailed t-value for α=0.05 and df = 9 is
Confidence interval for is given by :-
Hence, the 95% confidence interval for the true mean number of pushups that can be done is 8.56 to 21.44.
Answer:
6.85 is the answer to this.
Step-by-step explanation:
356*24*60=525,600 minutes in a year
Birth rate
3,600,000/525,600 = 6.85
Any number that is larger than -2.
For example y=0
-14 < 0-12
= -14 < -12
